利用油水井井位坐标绘制井位图 Inter_well
主要功能:1.利用油水井井位坐标绘制井位图;2.利用油水井注采液量数据绘制动态曲线图;3.利用油水井注采液量数据,根据容阻模型对井间连通性进行反演,求取注水井注水量平面分配系数,并进行可视化展示。
技术特点:软件自动读取井位信息及油水井注采液量数据,根据改进的容阻模型,利用基于遗传算法的混合优化算法来对模型进行求解,确定表征注采对应关系的参数——连通系数和时间常数,量化表征了注采对应关系,从而指导油田生产为油田开发管理者提供了科学的决策工具。(Main function: 1. wells wells wells by using the coordinate drawing graph; 2. the use of water injection wells drawing dynamic curve of fluid data; 3. the use of oil and water wells injection fluid volume data, according to the volume resistance model of inter well connectivity inversion for the water injection volume plane distribution coefficient, and visual display.
Technical features: the software automatically reads the information and the oil injection wells fluid volume data, according to the volume resistance model improved by genetic algorithm, the hybrid optimization algorithm to solve the model based on the determined parameters correlation characterization of injection - connectivity coefficient and time constant, the quantitative characterization of the injection production relationship, so as to guide the oil field the production provides a scientific decision-making tool for oilfield development management.)
